CHARLES J. BAUIVIGARTNER, 0F ERIN TOWNSHIP, MACOMB COUNTY, MICHIGAN.

FLUE-CLOSURE.

To all whom it may concern Be it known that I, CHARLES J. BAUM- GARTNER,a citizen of the United'States of America, residing atErin township, inthe county of Macomb and State of Michigan, have invented certain newand useful Improvements in Flue-Closures, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a flue closure, and the primary object of myinvention is to provide a double closure that can be easily and quicklyinstalled to prevent wind, soot or other elements from passing through aflue or stovepipe hole when not in use.

Another object of my invention is to provide inner and outer closuremembers for the ends of a stovepipe hole or flue, and to connect themembers so that both members will be frictionally held in engagementwith the faces of a wall having a flue or stovepipe hole therein.

A further object of my invention is to provide a simple, durable andinexpensive flue closure wherein effective means are employed forholding the closure members, particularly when installing the same, andI attain this and the above objects by a me chanical construction thatwill be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is ahorizontal sectional view of a wall having a flue and provided with thepreferred form of closure;

Fig. 2 is a front elevation of the outer closure member;

Fig. 3 is a horizontal sectional view of a wall having a flue providedwith a modified form of closure;

Fig. 4: is a front elevation of an outer closure illustrating amodification of my invention, and

Fig. 5 is an elevation of the inner closure member shown in Fig. 3.

The outer closure member comprises two semi-circular plates 1 and 2 withthe straight edge of the plate 1 overlappin the straight edge of theplate 2, so as to orm substantially a disk or circular plate. The innerfaces of the plates 1 and 2 are connected by hinges 3 and 4 so that theplates 1 and 2 may be folded toward each other, and in this manner theouter closure member collapsed in order that it may be placed through astovepipe hole 5 in a wall 6,

opened in the chimney flue 7 and placed against the outer face of thewall 6, as best shown in Fig. 1. To facilitate placing this member inposition and temporarily holding the same, the plates 1 and 2 haveresilient clips 8 adapted to frictionally engage the walls of thestovepipe hole or open ing 5.

The inner member is in the form of a circular plate or disk 9 adaptedfor engagement with the inner face of the wall 6 so as to seal the innerend of the hole or opening 5. The member 9 has an inwardly projectincentral hook 10 and adapted to connect this hook and the hinge 4 of theouter member is a coiled retractile spring 11. The end of the spring 11is detachable relative to the hook 10 and said spring is of suficientlength to permit of the free end thereof being extended and easilyplaced in engagement with the hook 10, so that when it is released, theretractile force thereof will positively hold the inner and outermembers against the wall 6, causing the marginal edges of both membersto positively seal the ends of the hole or opening 5.

In Figs. 1 and 5 of the drawing, there is illustrated a slightmodification of my invention in connection with both of the closuremembers. The plates of the outer closure member are provided withsemicircular clips or retaining members 12 adapted for engagement withthe walls of the hole or opening 5 and the inner member has bowedresilient or spring members 13 adapted to properly center the innermember relative to the axis or center of the hole or opening 5.

The flue closure in its entirety can be made of light and durable metalwith the inner closure member finished to present a neat appearance, andwhile in the drawing there are illustrated the preferred embodiments ofmy invention, it is to be understood that the structural elements aresusceptible to such changes, in size, shape and manner of assemblage, asfall within the scope of the appended claims.

What I claim is 1. A flue closure adapted for sealing the inner andouter ends of a stovepipe hole, comprising inner and outer members, theouter member composed of two semi-circular plates foldable relative toeach other and when open of a greater diameter than the diameter of thestove pipe hole so as to outer face of the Wall, retaining memberscarried by said outer member and adapted to engage the Walls of theStovepipe hole, and a retractile spring connected to a hinge of theouter member and adapted to be attached to the inner member.

In Witness whereof I afiix my signature 20 in the presence of-twowitnesses.
